Computational design of thermo-mechanical metadevices using topology optimization

• Topology optimization-based design of thermo-mechanical metadevices is proposed. The so-designed devices can be manufactured by using simple isotropic materials. performance has been analyzed via finite element method simulations. Such exhibit a good performance, when compared to more complex metadevices. present work conducted in order introduce novel approach for the mechanical conceived manipulate displacements field linear elastic materials subjected thermal gradients . an involves solution topology optimization problem where objective function defines error achieving prescribed displacement field, and device consists two macroscopically distinguishable candidate material distribution defined as continuous following solid microstructure (or material) with penalization (SIMP) method. are easy manufacture, since variables dictate distribution. Based on such it not necessary devise further ways simultaneously mimicking several effective properties, required coordinates transformation-based metamaterial methods. Although isotropic, behaves allowing desired manipulation field. As example, this applied elastostatic cloaking gradients, considering also thermo-dependent properties.
